La loi de Yerkes-Dodson : pourquoi la pression détruit votre stratégie

In 1908, Robert Yerkes and John Dodson published an article in the Journal of Comparative Neurology and Psychology that changed our understanding of the relationship between stress and performance. The curve forms an inverted U. Too little stress doesn't sufficiently activate the individual. Too much stress impairs their abilities. And the effect differs depending on the difficulty of the task. For simple tasks, a high level of stress remains beneficial. For complex or creative tasks, low stress is more advantageous. Creativity and strategic thinking are the first victims of high stress. Behavioral psychology describes the curve. Psychoanalysis explains what stress does to the individual. Sigmund Freud, in Beyond the Pleasure Principle, published in 1920, theorized that the psyche seeks to maintain moderate tension. Wilfred Bion, in The Sources of Experience, published in 1962, clarified why thinking breaks down under high stress. To think, the individual needs an alpha function that transforms raw data into thinkable information. Under excessive stress, this function becomes saturated. The individual no longer thinks, they react. Decisions made under high stress are reactions, not reflections. In this video, I explain precisely what Yerkes and Dodson demonstrated, what Freud and Bion illuminate psychologically, and why the 67% of French managers experiencing chronic overload, according to APEC 2023, is not an individual problem but a systematic managerial error. 00:00 Introduction 01:30 Yerkes and Dodson: The 1908 Discovery 04:00 The Inverted U-Curve Explained 06:30 Freud and Moderate Psychic Tension 09:00 Bion and the Alpha Function Under Pressure 11:30 The Death Drive and the Paradoxical Attraction of Pressure 14:00 67% of French Managers Chronically Overworked 16:30 Why Creativity Collapses First 19:00 Modulating Stress Rather Than Maximizing It Subscribe for insightful videos at the intersection of psychoanalysis and the business world. #yerkesdodson #yerkes #dodson #freud #bion #stress #burnout #psychoanalysis #management #performance
